DOUBLE-COMPARTMENT SINK INSERT Filed Dec. 9, 1954 "fT IFJENTOR. Em LemmaUnited States Patent Ofiice 2,784,418 Patented Mar. 12, 1957 2,784,418DOUBLE-COMPARTMENT SINK INSERT Edwin Luoma, Detroit, Mich. ApplicationDecember 9, 1954, Serial No. 474,124 1 Claim. (Cl. 4187) This inventionrelates to plumbing fixtures and particularly kitchen sink-s, and inparticular, includes an insert or liner for converting a conventionalkitchen sink into a double-compartment sink whereby one side of the sinkmay be used for washing dishes and the other side for rinsing the dishesand wherein either one or both of the compartments may or may not beused as may be desired.

The purpose of this invention is to provide an insert for kitchen sinkswhich converts a single-compartment sink into a double-compartment sinkin which the insert is adapted to be placed in the sink and removedtherefrom as desired.

Substantially all conventional kitchen sinks, particularly of the smallresidence and apartment types, are formed with a single compartment and,particularly in washing dishes, the entire compartment is partiallyfilled with soapy water and it is substantially impossible to wash andrinse dishes at the same time. Furthermore, in numerous instances,kitchen sinks are used for shampooing hair and washing clothes andparticularly clothes of infants and it is desired to place the washedpieces of garments and the like into a rinsing water as washing iscompleted.

With these thoughts in mind, this invention contemplates a lining ofrubber or other plastic material having a transversely disposedintermediate divisional wall and in which drain plugs are provided atboth sides of the wall wherein with the liner positioned in a kitchensink two separate and independent compartments are provided.

The object of this invention is, therefore, to provide means fordividing a kitchen sink into two compartments in which the dividingmeans is adapted to be removed and replaced as desired.

Another object of the invention is to provide an insert or liner fordividing a single-compartment sink into a double-compartment sink inwhich the liner is formed of a relatively resilient material wherebybreakage of dishes is reduced to a minimum.

A still further object of the invention is to provide a plastic linerfor dividing a single-compartment kitchen sink into a double-compartmentsink in which the liner is of a simple and economical construction.

With these and other objects and advantages in view, the inventionembodies a liner or insert having a base the upper surface of which isinclined downwardly toward the center and the lower surface of which isprovided with spaced longitudinally disposed ribs. The base is providedwith upwardly extended side and end walls and a transversely disposedpartition and drain openings are provided at low points therein.

Other features and advantages of the invention will appear from thefollowing description, taken in connection with the drawing, wherein:

Figure 1 is a plan view showing a kitchen sink with the improveddouble-compartment insert therein.

Figure 2 is a longitudinal section through the insert taken on line 2-2of Figure 1 showing the insert positioned in a kitchen sink, the sinkbeing shown in broken lines and the parts being shown on an enlargedscale.

Figure 3 is a cross section through the insert taken on line 3-3 ofFigure 2, also showing the insert positioned in a kitchen sink and thesink being shown in broken lines.

. chipping, cracking and breaking many Figure 4 is a perspective viewillustrating the formation of the double-compartment kitchen sinkinsert.

Referring now to the drawing, wherein like reference characters denotecorresponding parts, the improved double-compartment sink insert of thisinvention includes a base formed with sections 10 and 11 with end walls12 and 13 extended upwardly from ends of the sections 10 and 11, a rearwall 14, a front wall 15, and a transversely disposed intermediatepartition 16, the rear and front walls and partition also extendingupwardly from the base, and spaced longitudinally disposed ribs 17, 18and 19 on the section 10 and 20, 21 and 22 extended downward-1y from thesection 11.

Section 10 is also provided with a boss 23 having a drain opening 24therethrough and section 11 is provided with a similar boss 25 having adrain opening 26 therethrough.

The upper edges of the side and end walls of the insert are providedwith a continuous flange, as indicated by the numeral 27 and, asillustrated in Figure 2, the flange 27 is positioned slightly below theupper edge of a sink, which is indicated by the broken lines 28.

With the size of kitchen sinks substantially universal or the samethroughout the country, substantially a onesize liner is all that isrequired, however, it will be understood that the liners may be providedin diiferent sizes and may be formed of plastic, rubber or othersuitable materials.

With the liner formed as shown and described, it may readily be insertedin a sink, used and readily removed therefrom. The conventional sinkplugs are adapted to "be used in the openings 24 and 26 and the openingsmay be closed and opened as desired.

An insert of slightly resilient material would prevent dishes.

It will be understood that modifications, within the scope of theappended claim, may be made in the design and arrangement of the partswithout departing from the spirit of the invention.

What is claimed is:

As a new article of manufacture, an insert for converting a singlecompartment sink into a double compartment sink, said insert being ofunitary construction and being made of resilient material and comprisinga base including a pair of sections sloping downwardly toward the centerof the base, each of said sections being provided with a drainageopening, said drainage openings being arranged adjacent the inner endportions of the sections, a boss surrounding each of said drainageopenings, a plurality of spaced parallel longitudinally disposed spacingribs extended downwardly from the lower surfaces of said sections, saidinsert further including upstanding front, rear and end walls, atransversely disposed partition interposed between said end walls, andsaid partition being arranged at the junction of said pair of sections,the upper edges of said walls being provided with an outwardly extendedcontinuous horizontally disposed fiange, said insert adapted to beplaced in a sink and removed therefrom as desired.
